Quickly learn how to make 12V 50Ah lithium battery丨The whole process

Hi, everybody! This is Guangzhou TYCORUN Energy Co., Ltd. Welcome to watch our video today. In the video, we introduce the production process of 12V50AH lithium-ion battery in detail, and strive to let everyone understand how the lithium-ion battery is made in the shortest time. For what you don't understand, you can read our article below, you can further understand the whole process of battery production.
Here are a few steps to assemble the battery:

  • 1. Battery capacity
  • 2. Battery spot welding, parallel connection
  • 3. Battery cell insulation assembly, tin wire welding
  • 4. Install the BMS board
  • 5. Monitor BMS and package
  • 6. Insulation sponge pad and battery box package
  • 7. Super capacity after drying the battery
  • 1. Battery capacity

    After got the cell batteries, those batteries have done of capacity grading.

    2. Battery spot welding, parallel connection

    First of all,using UV machine automatic to connect the cells in parallel by spot welding.

    3. Battery cell insulation assembly, tin wire welding

    The battery cells which connected in parallel are separated by insulating paper and assembled together.
    Welded the battery with the data collection line together and then weld the positive and negative wires by solder wire in turn.

    4. Install the BMS board

    Then fix a BMS board on the top of battery pack with insulation paper that can collect data such as battery voltage and capacity.

    5. Monitor BMS and package

    The BMS protection board can monitor the battery status in every time, and provide protections such as over-charge, over-discharge, over-current, and over-temperature when necessary.
    To connect the data collection line to the BMS board and then test the voltage and internal resistance.
    After testing, use insulating waterproof glue to seal the exposed wires.

    6. Insulation sponge pad and battery box package

    Then paste the buffer insulation sponge on the bottom and put it into the ABS box, and connect the positive and negative wires to the positive and negative ports of the box cover.
    Then inject waterproof glue into the space around the box to fix the battery pack.

    7. Super capacity after drying the battery

    After 3 hours of drying, a battery that can be recycled for more than 2000 times is finished.

    Below are the details of our 12.8V50AH Li-ion battery:

    Eco-Friendly: Green energy with no toxic chemical material
    Super Long Life: 2000-5000 cycles, 10-year service life
    Rated capacity size:640Wh
    Battery length and width:229*138*208mm
    Battery weight: Approx. 6.0Kg
    High Safety and Stability: Grade A cells with built-in BMS(Battery Manage System) protection from over-charge, over-discharge, over-load, over-heating, short circuit. Low self-discharge rate 3%

    Lightweight, Easy to Install and Fast Charging: Great replacement of SLA/VRLA(lead acid batteries), with 2X Load Power,8X Cycle Life,1/3 Weight,1/5 Charging Time

    Application scenarios


    Ventilators are widely used during the epidemic. For people who are dying, ventilators are the most important epidemic to save lives. But have you ever thought about it. When the mains power is interrupted, without the support of direct current, the ventilator will lose its function. Therefore, the lithium battery can provide backup power for the ventilator. In an emergency, the high current discharge of the lithium battery can easily drive the ventilator and provide stable energy for a long time.

    3D printer is one of the most successful inventions of modern technology. No matter how crazy the idea is, 3D printer can help you realize it. For precision instruments, it is necessary to ensure its normal power supply. The promotion of lithium batteries provides stable energy for 3D printers. As backup power, lithium batteries have been silently protecting your equipment behind the scenes.
